First timer with an 11 year old dalmation that can eat, pee, and poop normally but has been vomiting a clear "mucusy" water mixture 5-10 times per day. She never seems uncomfortable and can eat normally and keep that food down. Her activity level and perky personality never seem to be affected. In other words, she seems so fine except for this wierd daily occurance. Any ideas of what we may be dealing with??
